Application filed August 16, 1920. Serial No. 403,'7?.

To all whom z't may concern.'

Be it known that I, HOWARD EARL HOOVER, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented a certain new and useful improvement in Display Devices, ofv which the following is a speciication.

rlhis invention relates to a display device and has for one object to provide a device for display purposes upon which an article may be mounted, so as to show at one and the same time, both the upper and the lower surfaces.

In' this particular illustration, there is placed upon the device a suction sweeper, which is providedI with a rotary brush. For advertising and display purposes it is desirable to show this brush inoperation, and the device is so arranged that the sweeper may rest upon it in the normal upright lworking position, and at the same time all surfaces of the machine will be visible.

Figure-1 is a vertical section of the device. f

Figure 2'is a section along the line 2-2 of Fig. 1. i l

Figure 3 is a side elevation' of the device with a suction sweeper in position upon it, with parts shown in dotted lines.

Figure 4 is a modification showing the principle of my invention applied toa table.

Like parts are designated by like characters throughout.

A is a display box having the open 'side A and transparent glass top A2. B is a compartment in one end of the display box defined by partition B2. B is an electric` lamp located within this compartment. C is a mirror adjustably mounted for rotation in the boX A, by means of the screws C C. '`C2 is a stop mounted in the box A to limit the movement of the mirror. 'D is a motor driven suction sweeper having the motor driven rotary brush D. rlihis suction sweeper is not described in detail as it forms no part of the invention, and is shown here only as an illustration of the use of this device.

An extension A3 may be provided at the rear of the box A as shown inFig. 1. This extension' permits of a greater movement of the sweeper or other article to be displayed, and for some purposes is desirable.

rlhe use and operaron of the invention is as. follows: l The display box will ordinarily be placed 1n some show window of a store, or in some public place. It will be so placed that passers by mayI look through the open side.

Upon the glass top ofy the device will be placed a suction sweeper or some article which it'is desirable to display. p The image of the bottom of the sweeper will be seen through transparent glass, and will show upon the mirror immediately below it, and will be reflected out of the open side of the box and thus the under side-of the sweeper is visible to passers by, at the same time that the rest of the sweeper is visible. By this means the operationof the brush in' the sweeper may be clearly shown while the sweeper is standing in the ordinary upright working position. It will of course be understood, that any device might `be used in connection with this display device. The mirror is so adjusted as to bring its image clearly within the view of an Observer.

Although l have shown in my drawings an operative form of this device, it will be obvious that many changes, both in dimension, shape and arrangement of parts might be made without departing materially from the spirit of my invention, and I wish therefore, that my drawings be taken as in a sense dia rammatical.

The lig t source is so situated that it will shine directly upon the object which is located on the transparent top and thus illuminate it',v but because of thepartition in the box, it will not shine directly upon the mirror, nor will it be visible through the opening, it will simply illuminate the bottom of the object on display and thus a brightly lighted image will appear on the mirror and so will be seen by the public. It will be obvious that this arrangement of a mirror, av transparent supporting plate and a source of light, might be made without an enclosed casing. The various parts might be arranged in an open frame work without departing from `the spirit of my invention.

in the modification or second form of the invention the transparent plate A2 is mounted preferably on the forward art of. a table F, and to this table is pivotaiily secured as at D the mirror C, the same beheld in any desired position by any combination of apparatus as for example by the bar E pivoted at E and provided with a slot E2 andwith a notched edge E3 to engage the pin E4 on the side of the mirror.

ln the arrangement of parts it is possible to move the object to be exhibited back and forth over the transparent plate and to one side of it. The table may be ot any desired size and so may the transparent plate'. With the table the artificial lighting scheme shown in Figures l to 3 inclusive is omitted. The device as illustrated in Figures l to 3 is more particularly adapted for exhibiting machines which are at rest, whereas the device shown in Figure 4 is especially adapted for exhibiting machines which are being run backvvardly and forwardly in the manner in which they are run backwardly and for- Wardly over the floor covering when in actual use. It will be understood, of course, that the device of Figures l, 2 and 3 could be so arranged as to permit the travel of the machineover a table or an extension over the top of the box to the rear of the transparent plate.

I have illustrated a transparent plate on which the object to 'be displayed is adapted to travel and such transparent plate is de sirable Where the suction sweeper is to be operated over a carpet in position, for part of the demonstration'or observation.

For some purposes it is desirable to remove the transparent plate and still show the machine in action. TWhen this is the case there may be substituted for the glass A2 plate any transparent material which Will support-the object to be exhibitedin upright position which will permit it to travel back and forth.. Thus the under part y adj aconty the neeaeaa of the object in question will be exhibited through the openingv where the glass is shown linthe drawings or through some part of the opening.,

l claim:

l. A display device comprising a substantially box like structure, a transparent plate, in the top thereof, on one side of which an obect to be displayed may be placed, a mirror under the transparent plate mounted in angular relation thereto, a partition in said box spaced from the top thereof, a light source positioned behind the partition and adapted to directly illuminate the bottom of an object which may be placed on the transparent plate and means preventing direct illumination of the mirror.

2. In a display device, an object to be displayed, a support for the object being displayed, a reilector positioned beneath the objectand in angular relation thereto, one end thereof closely approaching the'object being displayed and a light source positioned belenr the object being displayed and rearwardly of that portion of the reflector object.

3.' A display device including a transparent plate on one side of which the object to be displayed is placed and a mirror under said plate mounted so as to tilt to various angles with respectto said plate, and a light source adapted to illuminate the object through the plate, but shielded from direct' l illumination. of the mirror, and a casing which encloses the mirror,and a diagonal opening in said casing.

Signed. at Chicago, county of Cook, and State of lllinois, this 10th day of August,

HVVARD EARL HOOVER.
